Multi-Regional V2X BSM Routing for Cross-Border Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicles operating outside their home region face communication failures due to differing regional standards for Vehicle-to-Everything (V2X) Basic Safety Messages (BSMs), and navigational routes may not account for all relevant conditions or events, leading to incomplete information and potential operational failures.
Innovation Solution
Implementing a method for vehicles to generate and receive V2X BSMs compliant with a multi-regional standard, enabling communication across regions, and utilizing centralized processing to establish minimum-condition or minimum-event navigational routes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a vehicle transmits BSMs using its home region's regional standard when operating outside that region, then the BSM format complies with local regional standards, but communication fails because other regions cannot comprehend the BSM format
Solution Approach 1:
The patent applies parameter changes by dynamically switching the BSM format parameters based on the vehicle's current geographic location. The system detects the current region and changes the BSM transmission format to match the local regional standard, ensuring both communication reliability with local vehicles and adaptability across different regions.
Solution Approach 2:
The patent implements dynamics by making the BSM transmission standard dynamic rather than static. The system continuously monitors the vehicle's location and automatically adjusts the BSM format to match the current region's standard, enabling the vehicle to adapt to different regional requirements while maintaining reliable communication.
2Measurement precision
If an RSU provides navigation information only within its coverage area, then the information is accurate for that specific area, but the information is insufficient for evaluating overall routes that extend beyond the coverage area
Solution Approach 1:
The patent applies segmentation by dividing the overall route evaluation into multiple segments, each handled by different RSUs within their respective coverage areas. Each RSU provides precise navigation information for its specific segment, and the system integrates these segmented pieces of information to evaluate the complete route, maintaining accuracy while extending beyond any single RSU's coverage area.
Solution Approach 2:
The patent implements merging by combining navigation information from multiple RSUs covering different segments of a route. The system aggregates the precise local information from each RSU's coverage area to form a comprehensive view of the entire route, enabling accurate route evaluation even when the route extends beyond any single RSU's coverage area.

AI summary
A first vehicle-to-everything (V2X) device may operate in compliance with a first regional standard governing V2X Basic Safety Messages (BSMs) for a first geographical region, and a second V2X device may operate in compliance with a second regional standard governing V2X BSMs for a second geographical region. When the first V2X device is operating within the second geographical region, it may generate "global BSMs" in accordance with a multi-regional standard governing V2X BSMs. The second V2X device may process global BSMs generated by the first V2X device and may respond by generating its own global BSMs.
